makes destroying mad data not kill your db
ever tried to destroy/delete tens of millions of rows at once? w/ rails it sucks, this tries to make it better class Shredder < ActiveRecord::Base has_many :beers end The default is 500 rows at a time, feel free to change it. Shredder.destroy_amount = 2000 # woah, easy Now your regular rails destroy methods will only destroy/delete destroy_amount at a time. Shredder.destroy_all # instantiates x at a time, destroys one a time (no more instantiating the entire table ZOMG) Shredder.delete_all # just deletes x at a time straight w/ SQL, this way you won't lock up the db with your giant locking query (what a jerk) and in case you use acts_as_paranoid, it works with that too (destroy_all!) last thing, it works on associations too, like so: shredder = Shredder.find(:first) shredder.beers.destroy_all # this is what shredders do And it works on your :dependent => :destroy associations too. SHRED!
